Thanks. So with 130gr HHC I might be looking at 2,350 -2,400 FPS vs 2,500 from an 18" barrel. That isn't too bad and still is better than blackout or 7.62x39 with optimum barrel length.

I lose quite a bit with that particular load I’m my 8in. Roughly 40fps per inch. I average 30fps drop per inch with most loads. Still incredibly potent.

I get 2350 with a 110 SP in an 8". I'm not where I can get to by data on other bullets, but I doubt you'll be running 2350 with a 130.

I don't mean to be contrary .. please don't take offense. There is a significant change in velocities as you increase barrel length up to a point (most smaller cartridges somewhere in the 14"-16" area). The largest gains are at shorter barrel lengths as the majority of powder gets consumed. The increase in velocity really starts flattening out out past the 18"-20" line then its usually 10-15 fps/inch.. The adverse is also true on going short.

For example take a look at the 300BO data on the right side of the page. Going from 16" to 8" is a decrease of 400fps so more like 50fps per inch.

My first 300BO was a 8" SBR... what I learned is that I wish I had gone at least 10.5" for the extra velocity. The 300HAM'R automatically starts at higher velocities than 300BO for same given barrel length so not quite as detrimental. As to your question of 100 yards with an 300HAM'R (8" barrel) you shouldn't have any issues. Honestly, the most difficult thing with a shorty AR is trying to take a shot while resting the short handguard on window sill of blind....it really forces you to hug the front wall. As a result my hunting AR's have 16"+ barrels so there is 15" handrail available to help find a comfortable resting spot.

FYI: We did this test back in Nov 2018 so it's somewhat old data now and a shame we didn't cut the bbl all the way down to 8", but an interesting test.

All testing was done with the same barrel progressively shortened for no barrel to barrel variation and all ammunition for each load was from the same lot. Also shooting was done during a 5 hour period on the same day using a Labradar to minimize the effect of atmospheric conditions. All chronograph strings were 10 shots with the high and low shot removed for an average of the remaining 8 shots.

As you can see, as the bullet weight went up the barrel length had less effect on velocity. Averaging the 16.25” to 20” numbers it works out to 10.5 FPS per inch.

Thanks Bill! Great insightful data.

A little off topic but I'm seeking a hog bait that deer and horses won't eat. I've tried a couple recipes from the internet for "sour corn" which is basically fermented corn with some strawberry soda and jello added but maybe I haven't let it ferment long enough because it seems like everyone but the hogs eat it. Does anyone have a good recipe that only hogs will be attracted to and eat?

In my misspent youth I used to hunt with a 30-30 using 170 grain bullets which were the most accurate factory load for my rifle. I was wondering if there is any 170 grain bullet that will work with the ham'r?

None that I'm aware of, I spent quite a bit of time testing the Hornady 160gr FTX which is designed for the .30-30, it kills hogs great, but I never was able to achieve acceptable accuracy. About 1.75" is as good as I could get consistently. I tried 1-11, 1-11.25, 1-12 and 1-13 twist barrels. I think this cartridge is max'd out with 150gr bullets.

Thanks for the quick reply! I was just curious but I've pretty much settled on the 150gr Speer 2022 as my go to bullet. Reasonably priced and shoots one hole groups at 50yds out of my barrel.

The environmentally friendly answer is unfortunately “No”. The morally ambiguousl answer is “add Diesel” to your corn. Apparently, hog/pigs are not put off by the smell or taste of diesel fuel mixed in with the corn. Deer and other wildlife won’t touch it.

My problem is I like to eat the pigs, and I try not to pour chemicals down the sew drain anymore. There is also the issue of if this is a place you are planning to hunt pigs and deer then you may have ruined your best area with lingering smell of the ground permeated with diesel,

I simply set the feeder to throw at night if I am focused on pigs instead of deer. Fatter rabbits, deer and raccoons are easier to see with night vision!

I've heard the diesel trick but never thought about mixing it into the corn. The way I heard it used is to create a wallow using diesel and even covering it with dirt to encourage the pigs to root. Probably not very environment friendly unless you built some sort of container so it wouldn't leech into the soil.

My "sour corn" bait is quite a ways from the feeder so I'm not worried about discouraging the critters although from what I've seen they don't seem to mind eating close to the nasty stuff.

To make the corn real sour and nasty, I’d pour a beer into the bucket and screw the top down. Gets really stinky in the hot Sun after a couple of days.

And I put diesel on the corn at times, or the coons would eat it all. Dang coons. I didn’t notice any taste diff eating pigs that ate the diesel-ized corn. If a fellow is gonna worry about what pigs eat, best you don’t ask what they eat. And you better quit eating chicken from the market.

Get em fat and drunk huh? Sounds like a plan to me!

Maybe I've just not been letting it sit long enough. How long do you ferment the corn?

I ferment it till it really really stinks. It’s kind of soupy and nasty by then. If you are married, don’t go in the house if you have slopped some on you.

Well…Ok, back on topic. IF you are carrying your 300 Hamr, you can go in the house with the stinky corn smell on you.

For anybody with short barrels. I got some good data with the controlled chaos offerings today. Virtually every other 110gr load hasn’t come close to these numbers for me. 250-350 fps gain over comparable loads in my similar 300 BO.

Thanks for the info. Is this out of your 8" bbl? I've found the 110CC to be the most accurate out of my 8" out to 100 yards. I've not had any data on fps out of an 8" for the 110CC. Those are great numbers. The HHC was a close second in a group at 100. And I am currently only shooting factory loads.

I finally got my rifle back, and I am thrilled so far. The gas port is a bear to drill due to a hardend gas block, so it's a suppressed only or manually cycled affair, but thus far it has been amazing. I put about 150 downrange to function check it and found that accuracy with with pre-fireformed loads (sized Hornady 5.56 brass and WT brass) was about 1.5 MOA using a .300 BLK load of CFE BLK and Hornady 150 grain FMJ-BT bullets (i.e. loads whose sole redeeming quality is that they safely expel bullets from the gun). This is an 18" 1-10" Shilen barrel. I suspect that with actual worked up loads and "real" bullets (in this case 150 grain HDY SSTs) this thing will shoot MOA or better. The irony is that I got my great-grandfather's .30-30 1894 back at the same time from the same gunsmith, and explained to them that the two rifles, while very different in appearance, are in fact the exact same thing: a handy, intermediate caliber carbine capable of taking deer sized game to 200 yards.

I'll post precision and velocity/energy numbers when I get them, as well as my results with range brass loads. I'd like to thank Mr. Wilson again for developing a great cartridge and for being involved with the community after the fact. These calibers (.300 HAM'R and 7.62x40) are a breath of fresh air and in some ways a return to sanity. It seems as though everything is going for 1000 yard capability or minimal report, and the reality is, the ballistics of the .30-30 are just as lethal to the animals that we hunt today as they were 130 years ago. The use of common, standard components in a common platform means that people who want to load and shoot these calibers can do so without being locked into 3 different proprietary components. In an era characterized by overkill, vendor lock-in, and baseless advertising, Mr. Wilson instead developed a round that is sufficient for task, cost-effective, non-proprietary and practical. Thanks.

Has anyone tried the new Hornady 110 grain CX bullet?

Well said sir! I will add that I am impressed how WC made it important to make ammo (when you could not find a single round of 300 BLK anywhere) and components when the market was dry. Not everything was in stock but something was always in stock. Their dedication to their customers is a shining light in the industry.

I haven't seen any yet, but I think the nose will be too long to be able to load under 2.255" before the nose taper goes below the case mouth. Same problem most high BC tipped bullets have.

I believe MidSouth has them in stock. Thank you for your input!

Is about time those pigs came back, guess I need to knock the dust off mine.
